Abstract: Objective:To find the better imaging method for the diagnosis of sialolithiasis by comparing the 3 different imaging methods.Methods:32 cases of salivary calculus were examined by sonography,X-ray and cone beam computed tomography(CBCT),the sensitivity,specificity,positive predictive value,negative predictive value were compared among the 3 methods.Results:The sensitivity and negative predictive value of cone beam computed tomography(95.8％ and 80％) was significantly higher than those of sonography(83.3％,50.0％) and X-ray(58.3％,20％)(P ＜ 0.05).Of three imaging methods there was no statistical difference in specificity and positive predictive value.Conclusion:CBCT is more sensitive than sonography or X-ray in the diagnosis of sialolithiasis.
